The depression in the road surface varies in shape and size between different manufacturers and their light models. In case of the wireless lighted crosswalk , once the step of securing the . The TS-4is typically used in crosswalk applications, but is often used in school zone or railroad crossing, lane control for bridges and tunnels, wrong way warning, and toll booth or toll way lead-on applications.
